## Database

- **Schema**: Drizzle schema lives in `src/**/*.sql.ts`.
- **Naming**: tables and columns use snake*case; join columns are `<entity>_id`; indexes are `<table>*<column>\_idx`.
- **Migrations**: generated by Drizzle Kit using `drizzle.config.ts` (schema: `./src/**/*.sql.ts`, output: `./migration`).
- **Command**: `bun run db generate --name <slug>`.
- **Output**: creates `migration/<timestamp>_<slug>/migration.sql` and `snapshot.json`.
- **Tests**: migration tests should read the per-folder layout (no `_journal.json`).
